CORN-EUSKING MACHINE.

Specification of Letters Patent.

Patented Nov. 4: 1913.

f Application filed January 14,1913. Serial No. 741,975.

7 To all whom. it may concern Be it known that I,- THEODORE STnIoHnN, a citizen of the United States, residing at Alton, in the county of Sioux and State of Iowa, have invented certain new and useful Improvements in Cor'n-Husking Machines, of which the. following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a machine which is used for removing the shuck from an ear of corn.

The principal object of the invention is to provide an improvement of the class specifled which is so constructed'that the ears of corn will be fed into the machine in. the right position for removing the shuck and in which the shuck will be entirely removed from the ear, and the ear of corn then dropped into a trough through which a traveling conveyer passes for carrying the ear of corn to a suitable receptacle.

Another object. of the invention is to provide an improved type of husk removing machinery so that thehuskv will be entirely removed without damage to the ear of corn.

Another object of the invention is to provide an improved means for holding the ear in the proper position for removing the husk.

.Another object of the invention is to provide an improved means for yieldably holding certain of thehusk removing rollers in their proper position, thus permitting the rollers to have enough give to permit anea'r of corn to pass through the rollers if by any chance it should become jammed between two of the rollers.

With these and other objects in view this invention consists of certain novel combina-. tions, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

- In the accompanying drawings :Figure 1 is a front elevation of the corn husking machine. Fig. 2 is a rear elevation of the husker. Fig. 3 is a top plan view. Fig. 1 is a sectional view along the line 5'5, in Fig. 1. Fig. 5 is a sectional view through line 66, in Fig. 3. Fig. 6 is a vertical sectional view through the machine along the line 7-7, in Fig. 1. Fig. 7 is a perspective View of one of the vertical springs which assists in. holding the ears of corn in the proper position while the shack is being removed. Fig. 8 is a diagrammatic View showing the manner in which the ears of corn are held while the shuck is being re moved.

Referring to the accompanying drawings it will be seen that this invention comprises the base having the side bars 15' which are connected. by the base board 16 and from which there extends the vertical sides 17 which are connected by the cross bars 18 and 19. The cross bars 18 and 19 not only conneot the sides 17 but also form supports for the rollers 20 and 21 which will be described in detail farther on. A trough 22 is mounted beneath an opening running transversely of the base board 16 and is provided with a guiding plate 23 which extends beneath the cross bar 18 in order to guide the ears of corn into the trough 22. The bottom of the trough 22 is formed of an endless conveyer belt 24 which travels around pulleys 25, thus carrying the ears of corn to one side of the base board. A sprocket wheel 26 is mounted upon the shaft of one of the pulleys 25 and is connected by a sprocket chain 27 with a sprocket Wheel 28 mounted in bearings 29 at the lower end of a trough 30 through which an endless conveyer belt 31 passes. This conveyer belt 31 passes over pulley wheels mounted at the ends of the trough 30, one of the pulley wheels being mounted upon the shaft of the sprocket wheel 28. It will thus be seen that the traveling of the endless conveyer belt 24 will cause the endless conveyer belt 31 to also travel throughits trough 30, thus conveying the ears of corn up the trough and depositing them in a suitable receptacle.

The rollers 20 and 21 are rotatably mounted between the cross bars 18 and 19. The rollers 21 have their pivot pins 32 passing through slots 33 in the cross bar 19 and carry bearing blocks 34: which are engaged by the springs 35 to normally hold the rollers 21 in'a vertical position. By this construction the rollers" 21 are permitted to have a certain amount ofgive so that if an ear of corn becomes jammed between the rollers 20 and 21 the roller 21 may have suflicient give to permit the corn to pass between the rollers. Gear wheels 36 are mounted upon the pins 32 and mesh with the gear wheels 37 mounted uponthe pivot pins of the rollers 20 to cause the rollers 20 to be rotated in unison with the rollers 21. It should be noted that these rollers 20 are provided with a plurality of teeth 38 which are so positioned that when the rollers 20 and 21 are rotating the teeth 38 will pass the'reduced portions of the rollers 21. It should also be noted that these. teeth are provided with beveled outer edges which will assist in causing the ears of corn to be worked gradually downward as the shuck is removed.

A. powershaft 39 is rotatably mounted in bearings 40 above the cross bar-19 and is provided with beveled gears'41 which mesh with the beveled gears 42 mounted upon the pins 32. "When this power shaft 39 rotates it will cause the rollers 21 and 20 to be rotated, thus causing the teeth 38 to catch the corn shucks and remove them from the ears of corn; A pulley wheel 43 is mounted upon the outer. end of the power shaft, thus permitting the power shaft to be-rotated by a belt or other suitable means leading from a source of power.

Upper and lower supportingbars44 and 45 are secured tothe side bars 17 and form bearings for the'vertical rollers 46 around which the endless conveyer belt 47 passes. This conveyor belt 47 travels close tothe inner faces of the rollers 20 and 21 and engage the ears of corn as shown in Fig. 8 to hold the ears of corn against the resilient strips 48 which are secured to the upper and lowerbars 18-a-nd19 in such a position that the teeth 38 can readily engage the corn shucks. It will be noted that by an inspection of Fig. 8 that the ears of corn do not pass into the space between the rollers 20 and 21 a sufficient degree to permit the ears to be jammed and that, therefore, there is no danger of the machine being clogged and prevented from operating. The slots33 and springs 35, however, have been provided to permita very small earto pass through the rollers in case a small ear is placed in themachine and passes between the rollers 20 and 21 to such an extent that it would be jammed if it were not for this provision. A bevel-ed gear 49 is mounted upon the pivot'pin of one of the rollers 46 and mesheswith' a ibeveledigear 50'mounted upon a stub shaft'hl C21;Ill6Cl.byil3l18'UppBI' bar 44. A gear wheel'52 ismounted upon this stub shaft 51 and meshesxwit-h a gear wheel 53" mounted upon a shaft 54. This shaft 54 extends'transversely across the machine with its end portionsjournaled in the strips 44 and isprovided at one end with a sprocket wheel which is connected with a; sprocket wheel 56 mounted on the power shaft 39 by a sprocket chain 57. It will, therefore, be seen-that the power shaft-rotates the-rollers 20 and 21 andthrough the sprocket chain 57 transmits power to the shaft 54, which shaft in its-t-urntransmits power to the conveyerr47 through the medium of the gear wheels-52 and 53 and beveled gears 49 and 50. The shaft 58 of one of the rollers 46 extends beneath its supporting bar 45 and'is provided with a beveled gear 59 meshing with a beveled gear 60 mounted upon the axle of the rollers 25. Power, will therefore, be transmitted to the conveyer 24 when the power shaft is in motion and thus the entire portion of the machine so far described is operated by power transmitted from the a power shaft.

A frame comprising'theside bars 61' and connecting plate 62and bottom 63 is piv'-- otally mounted upon-the-shaft 54 byhaving the'shaft pass through the side bars andis held in the desired incline by having its lower edge resting in a selected notch ofthe bracing bar 64. Thisframe forms a ho per in which the ears of corn are dumped mm a chute 65' and is divided into a plurality of troughs 66 through which the conveyer chains 67 pass. These conveyer chains pass over sprocket wheels: 68" rigidly mounted upon the shaft 54 and' also" aroundrsprocket wheels 69 mountedupon a shaft"70"jour naled in bearings? 1 atthelower end of' the hopper. The chain conveyers 67- arepro vided with spurs 72 whichxspursrengaging catch into the leavesrforming the shucks for the ears of corn anddraw the ears-upthe troughs 66 until the ears reach the top where they will fall over the upperedge of the trough andon to the spouts 73lstruck from the metal plate 74 and secured toethe supporting bars 44 above the rollers 146; These spouts are positioned opposite the spaces between the sets of rollers '20 and21 and to one side of the resilient strips 48: Therefore, when the ears of corn fall 5 onto the spouts 73 they will be guided into. the space between the rollers and, therefore, in the-proper place for the shucks-hto benre moved.

From the above descriptionit will beseen that the ears of cornare dumped into: the hopper andare: then carried up the trough 66 by the conveyerchains 1 67 until they reach the top and will then fall'into the spouts 7 3 and be guidedinto' the space between the conveyer belt 47 and the-rollers 20 and '21. The: belt =47 1 will hold the ears of corn tightly against the resilient strips 48 and the teeth 38 will catch" the=-leaves forming the'sh'ucks and tearthem off carrying them through to the outside of the roll' ers where they will dropeither upon the ground or'a suitable receptacle. The ear of corn graduallywvorks downwardly'until when all i the shuck's have been-1 removed!- it falls into thetrough 22upon-theconveyer belt 24 which :belt carries them tothe 'con veyer'belt '31 traveling through the trough 80. This beltBl will carryxthe ears of corn up the trough 30 and dump them into suitable receptaclea: A machine has, there fore, been provided which will remove the shuck from the ear of corn and then deposit the clean ear into the trough through which a traveling conveyor belt passes to carry the ears to a suitable receptacle provided to receive them.

Having thus described the invention what is claimed as new, is

1. A corn husking machine comprising a frame, husking rollers rotatably mounted in said frame, a traveling apron carried by said frame and extending parallel to said rollers, resilient strips carried by said frame and positioned between said rollers and apron for holding ears of corn in the proper position to be operated upon by said rollers,

and operating means for said rollers and apron.

2. A corn husking machine comprising a frame, husking means carried by said frame, an apron extending substantially parallel to said husking means and movable transversely thereof, and means between said apron and husking means for holding an ear of corn in the proper position to be operated upon by said husking means.

In testimony whereof I hereunto affix my signature in presence of two witnesses. I
